(LifeScript Health News) As if you needed another reason to drink red wine. Resveratrol, a phytochemical found in the skin of red grapes and red wine, might protect against breast cancer cell formation, according to a study by the University of Nebraska Medical Center. It’s also sold in a purified form as a dietary supplement. The study found that taking just 10 umol/L of resveratrol – a fraction of the amount in a supplemental pill – may stop the growth of cancer by preventing estrogen from attaching to DNA, which is the initial stage of breast cancer formation.
